RIBBON-INKING ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 341,630. dated May 11,1886.

Application filed August 3, 1885.

To all whom it may concern.-

Be it known that I, LEONARD BAILEY, of Hartford, county ofHai-tford,State ofCon uectiout, have invented certain new and useful Improvementsin Ribbonlnking Attachments for Typewriters, of which the following is ade scription, reference being had to the accompanying drawings, where-Figure l is a plan or top "iew of part of a type-writing machine of thekind known as the Caligraph, with my improved device attached inposition for inking the ribbon. Fig. 2 is a view in central verticalsection through the reel, thetype-writer frame, and the inkingattachment. Fig. 3 is a detail perspective view, on enlarged scale, ofthe frame used to hold the rolls. Fig. 4 is a detail seetional view ofthe inking-roller and its cover, the latter being removed.

The object of my invention is to provide means for inking the ribbon ofa typewriting machine without removing the ribbon from the reels on themachine; and to this end my invention consists in the novel constructionof parts and their combination, as will be hereinafter fully described,and specifically pointed out in the claims made thereto.

In the accompanying drawings, the letter a denotes the frame of one ofthe class of typewriting machines known as caligraphs, so much only ofthe frame and the operating parts of the machine being shown as isnecessary to illustrate my invention.

The letter 1) denotes one of the ribbonreels appurtenant to the machine,and c the ribbon, which is of usual form and material and is stretchedacross the machine between the two ribbon-reels on its opposite sides,in the usual manner.

At one side of the machine, about in line with the carriage and in thesame vertical plane with the ribbon, is supported an inking roll, (1,preferably by securing it in bearings in the roller-frame e, that isdetachably secured to the frame of the machine a. This rollerframe 6 ismade, preferably, of metal, cut or cast to shape, with the base 6, thearms 6-, extending from the base, and the clamp f. The latter in theform shown consists of the clampscrew f, that is seated in a threadedsocket in the downturned flange on the base of the frame Serial No.173,327. (No modeLl and cooperates with the flange or pin 6 in attachingthe roller-frame to an object. On

the arms 6* are formed the bearingsgg, for the inkingroll d and theguide roll d. The upper part, 6, of this roller-frame corresponds withthe lower part in general outline, and is reinovably secured to it bymeans of the screw 71, the several parts being clearly shown in Fig. 3.

The pins that form the bearings g are long enough to project through theholes 9* in the upper part of the frame when'the latter is secured tothe lower part, and thus the two parts are kept in proper relativeposition.

The inkingroll d is made up of the tubular central ink-receptacle, (1having in its walls a number of perforations, d, and this ink-receptaclehas a porous cover, (1, compl'etely inclosing it on the outside andextending between the end flanges, d d", of the roll. This porous coverd of the roll is preferably made of felt, which is sufficiently porousand absorbent and retains in about the proper de gree the ink whichflows into it from the inside of the receptacle within the roll, but anymaterial other than felt having such qualities may be used equally wellin its place as a cover. The roll is provided with the central pivots,(1 one borne on the fixed end and the other on the removable end, whichis held, preferably, by the screwstem extending within the threadedsocket in one end of the receptacle.

The ink-roll is preferably protected when not in use for inking purposesby means of a tubular cover, (i that may be slipped upon the roll fromeither end, and is preferably of metal.

' The guide roll d is of any convenient material-as metal-has suitablepivot-bearings, is preferably of the same size as the inkingroller, andis mounted in the frame by the side of the inking-roll, as shownin theaccompany ing drawings. The office or function of the guide is to changethe direction of the ribbon, so as to bring its upper surface in contactwith the ink-roll. This guide-roll is not essential to the operation ofmy device, as the ribbon is usually absorbent enough to enable the inkthat is applied on one side to pass through it and thoroughly permeateit, so that either side purposes part of the frame secured to the frameof the typewriting machine. A loop of the ribbon is then passed over theinking-roll, which is placed in the bearingg in the frame,and anotherloop under and over the guideroll, which is then placed in its hearingsin the frame. The cover-plate is then secured in position, as illustrated in Figs. 1 and 2, and by turning the reel the ribbon is drawnback and forth over the inking-roll, the cover of which was removed, ofcourse, before placing it in position for use. By reversing this processthe rolls may be removed from the frame, the cover of the inking-rollplaced in position, and one or more of the rolls, replaced in the frame,to serve as supports or guides for the ribbon in place of the usual wirewhich holds it at the proper height for use in the machine.

I do not limit myself to the particular form of the roller-frame or tothe particular construction of the ink-roll herein shown and described,as it isevident that the form of the frame and the relative arrangementof the rolls can be changed without, however, the exercise of inventionto adapt the frame or rolls to different kinds or forms of type-writingmachines.

By the term ribbon-reel, as used in the following claims, I mean to beunderstood as claiming in the combination with the other elements thereel or any equivalent support for the ribbon in its passage through themachine.

I claim as my invention- 1. The combination, with the ribbon andribbon-reels of a typewriting machine, of a removable frame bearing theinking-roll and the guide-roll, and a clamp whereby said frame isattached to the frame of the machine, all substantially as described.

2. In combination with the ribbon and ribbon-reel of a type-writingmachine, the rollerframe with the clamp for attaching it to the machine,the removable upper part of the frame, and the ink-roll held in bearingsbe tween the parts of the frame, all substantially as described.

3. In combination, the roller-frame with the clamp device, the removableupper part of the frame, the guide-roll, and the ink-roll with thecentral perforated ink-receptacle with porous and absorbent cover, therolls being supported in bearings between the parts of the frame, allsubstantially as described.
